CMC spokeswoman Rebecca Denning says the powers can have a negative impact on marginalised groups.

"[The include] homeless people, young people and Indigenous people," she said.

Another report has recommended new protocols to ensure ministerial staffers do not inappropriately influence public servants.

Bligh promise

Premier Anna Bligh says the State Government will implement the CMC's recommendations about interactions between ministerial staffers and bureaucrats.

"We want to make sure that our system is the best in the country," she said.

"The legislation that we passed is certainly cutting-edge in relation to accountability of ministerial staff.

"This report gives us an opportunity to take that further and we will."

Sports rorts affair

Meanwhile, the final CMC report into the so-called "sports rorts affair" has confirmed no legal action will be taken.

The CMC examined former ministerial adviser Simon Tutt's role in the awarding of a $4.2 million grant to Queensland Rugby Union (QRU).

It found senior public servants were unduly influenced by Mr Tutt who had close links to the sport.

Mr Strange says the evidence is not considered strong enough to lay charges, and because Mr Tutt no longer works for the government, he cannot be disciplined.

"There is provision now - the law provides that if someone has resigned, disciplinary proceedings can still be taken against them and can potentially result in a disciplinary declaration for their record," he said.
